Castlewellan Forest Park is located in Castlewellan, Northern Ireland. It contains the national Arboretum of Northern Ireland, started in 1740, which contains trees from Asia, North and South America, and Australasia. Giant sequoia were planted in the 1850s. They are used by treecreepers, who burrow into its bark and make nests. The gardens were reopened in 2013 after undergoing maintenance.[2]
